Gousumv COMBINATION TRUCK WHEEL UNLATCIIING I-IOOK AND PETCOCKRELEASE DEVICE This invention relates to collapsible extension devices,and more particularly to a combination truck wheel unlatching hook andpetcock release device for trailer trucks.

It is therefore the main purpose of this invention to provide acombination device which serves as an extension to pull the lever on atrailer truck fifth wheel and also to engage the petcock drain on theair tank of the vehicle.

Another object of this invention is to provide a device of the describedtype which will have a portion carried by an elongated wooden rod thatwill extend in order to reach the lever on the trucks fifth wheel inorder to unlatch it, thus preventing the operator from getting theirclothes soiled.

Other objects of the present invention are to provide a combinationtruck wheel unlatching hook and petcock release device which is simplein design, inexpensive to manufacture, rugged in construction, easy touse and efficient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawings wherein:

FIG. 1 is a horizontal view of the present invention shown in elevationand partly broken away;

FIG. 2 is a view taken along the lines 2-2 of FIG. 1;

FIG. 3 is a horizontal and elevated view of the rod portion of thedevice shown removed from FIG. 1,

FIG. 4 is a view taken along the lines 4-4 of FIG. 3;

FIG. 5 is a horizontal and elevated view of the handle of the devicewith other components removed therefrom; and

FIG. 6 is an enlarged transverse view taken along the line 66 of FIG. 5.

According to this invention, a combination truck wheel unlatching hookand petcock release device 10 is shown to include an elongated woodenhandle 11 having a metalic sleeve 12 secured fixedly to end I3. Sleeve14 of suitable metalic material, is secured fixedly to end 15 of handle11 and a transverse slot 16 across end 15 serves as engagement means forthe air tank petcock of the vehicle.

An opening I6 transversely through end 15 of handle ll provides a meansfor receiving a pin (not shown) in the event that sleeve 14 is removed.

Handle 11 carries an elongated rod 17 having a hook 18 for unlatchingand pulling the lever on truck fifth wheel (not shown). Rod 17 isslidabie within an elongated slot 19 of handle 11 and rod 17 is alsoprovided with a ring portion 20 which encircles the outer periphery ofhandle 11 and also serves as stop limit means against sleeve 12 when rod17 is extended completely.

In use, device 10 is handheld by means of its handle 11 and rod 17 maybe extended to its entire length wherein the ring portion 20 will abuttwith sleeve 12 fixedly secured to end 13 of handle 11 in order tounlatch and pull the lever on the trueks fifth wheel without the usersclothes becoming soiled.

When device 10 is reversed, the end 15 with its slot 16 may engage thepetcock of the air tank in order to bleed the air therefrom.
